spam filter server side
Not all email clients provide sophisticated ways to filter emails.
In these cases it is possible to act upstream.
The “Authorized senders” feature allows you to receive messages
only from the senders you have previously authorized:
All the regular messages will arrive as usual in your inbox.
All the spam messages will go to a different mailbox.
No emails will be lost.
You may read the discarded messages mailbox once a day.
You will save so much precious time.
